The system will be disabled by the control electronics the first time the driver uses the brakes after he has activated the system.
It will only be enabled if the driver is less than one second behind another at any of the pre-determined positions around each circuit. The driver may only activate the adjustable bodywork in the race when he has been notified via the control electronics (see Article 8.2) that it is enabled. The adjustable bodywork may be activated by the driver at any time prior to the start of the race and, for the sole purpose of improving overtaking opportunities during the race, after the driver has completed a minimum of two laps after the race start or following a safety car period. – Any alteration of the incidence of the uppermost closed section may only be commanded by direct driver input and controlled using the control electronics specified in Article 8.2. – The design is such that failure of the system will result in the uppermost closed section returning to the normal high incidence position. – When viewed from the side of the car at any longitudinal vertical cross section, the physical point of rotation of the rearmost and uppermost closed section must be fixed and located no more than 20mm below the upper extremity and no more than 20mm forward of the rear extremity of the area described in Article 3.10.2 at all times. The controversial new driver-adjustable rear wings are explained in article 3.18:
The regulations also include a raft of new safety measures including extra wheel tethers and tougher tests for the survival cell.
